> Hi All R guru's, 
> A couple of simple questions which I cannot find answers to in "an
> introduction to R" or in the reference manuals.
> I am running R on Win95, and have plotted up quite a nice box and whisker
> plot:
> char<-read.table("n:/reddinm/grifpr~1/survey/char.txt")
> attach(char)
> boxplot(Al,Fe,OC,pH, range=0,xaxis=FALSE,
>   ylab="Proportion of Unirigated Soil
> Characteristic",xlab="Characteristic")
> nom2<-c("Al","Fe","OC","pH")
> axis(1,1:4,nom2)
> abline(h=1,lty=2)
> The problems are these, how do I change the line width (lines are all too
> light).  I have attempted putting lwd=2 or something higher inside the
> boxplot statement....
> which it swallows without any complaints...it just doesn't seem to change
> anything, either on the screen or when printed out.
> Second problem, I find that the text quality when I export to a PNG file
> is pretty bad...not good enough for publication.
> I thought that I might be able to get HErshey fonts to improve this...but
> can't get them to work.  
> Final question: I cannot get R to swallow the addition of
> a font.lab(xxx,xxx) statement in the boxplot function......how do I get it
> to use Sans Serif, and produce high quality output?  How do I use the 
> font.lab command and the related commands.
> Thanks for your help.  It looks like a nice package from what I have seen
> so far, so I'm keen to learn to 
> use it.
